The clue is in the Instrument Approach Charts, CAT C/D aircraft CAT 1 ILS, DA 680/690FT, an aerodrome elevation of 153FT (29 threshold significantly lower) and no apparent significant obstacles in the approach area, make a sharp left turn at DA, and get the h*ll out of there fast!
I can see where you're coming from but a higher minima shouldn't exclude it's use as an alternate should it?
Sure it's a consideration with marginal weather or single-engine performance but there are many major international airports with restrictive minima... Hong Kong, Nice, Innsbruck to name a few. If we'd consider them as Destinations on two engines why not as alternates?
Or am I missing your point?
